Question

For a pendulum, when is the gravitational potential energy (GPE) greatest and kinetic energy (KE) least?
A. At the lowest point of the pendulum’s swing.
B. At the highest point of a back swing.
C. At the point where the pendulum changes direction.
D. When the pendulum first begins its downward swing.



It's B right?

Answer 1

where it downward swing begins cuz, at the peak of motion it stores potential energy and when it falls from there at that time potential energy is maximum and that potential energy is converted in to kinetic energy during the downward movement with highest kinetic energy at bottom

Answer 2

@taylorrrr clear?

Answer 3

Yes I understand know, thanks cfor the help!!

Answer 4

:) YW

Answer 5

Now let's work on your grammar....
